The mother of a homeless man who heroically helped those caught up in the Manchester Arena terror attack is appealing for help to reunite her with her long lost son - who she didn’t know was sleeping rough.

Chris Parker, 33, was begging in the foyer area of the music venue when the bomb exploded, the M.E.N. reports.

Despite being knocked to the ground by the blast, he got up and sprinted towards injured music fans.

At least 22 people - including children - were killed in the horrific attack.

A further 119 people were injured as a result of the suicide bombing , which happened moments after an Ariana Grande concert.

Details of Chris' heroic actions have been widely reported and a GoFundMe page has been set up for him.

His mum Jessica contacted the M.E.N. after spotting the story - and her son’s picture - on Facebook.

She said she had no idea Chris was homeless after losing contact with him a few years ago.

Jessica, 57, is pleading for help to get back in touch with her son and is planning to travel to Manchester from her home in Norfolk to see him.

She used to live in Walkden in Salford with Chris and her other son before moving back to her home county of Norfolk.
